External Signals Strategy Tester backtest results, every cell

There is no cloud of cells to draw. The frame below says why.

How External Signals Strategy Tester works

Rules in this group usually work like this. This one does not sit in the usual groups. The buy and sell lines below are what it is. Read it the same way as the others: what it assumes, how many trades it took, and what happened on many coins and chart speeds rather than on one. The next paragraph is this particular rule, which can be narrower than the group.

It can buy, and it can bet on falling prices. It acts only when several checks agree at once. The exact line is in the list below, in the author's names, and you can skip that list. It gets out when another set of checks agrees. That line is in the list below too.

Each trade uses the whole account. It holds one trade at a time.

The exact condition, from the code

Same rule, translated from the code, in the author's names. You can skip this list if the paragraph above was enough.

• Enters long when Reverse Position on Opposite Signal (off) and a short position is open and Buy Signal crosses above 0 and Enable Long (on).
• Enters short when Reverse Position on Opposite Signal (off) and a long position is open and Sell Signal crosses above 0 and Enable Short (on).
• Enters long when no position is open and not (reverse done) and Enable Long (on) and Buy Signal crosses above 0.
• Enters short when no position is open and not (reverse done) and Enable Short (on) and Sell Signal crosses above 0.

• Closes the position when Reverse Position on Opposite Signal (off) and a long position is open and Sell Signal crosses above 0 and Enable Short (on).

How the backtest was run

Every strategy was tried the same way, on the settings the author published.

The years are October 2021 to June 2026. The prices are from Bybit, for 13 widely traded coins, mostly on hourly, 4-hour and daily charts, with some faster charts. That was 47,242 tries. The window stored in the files is 2021-09..2026-06.

599 rules produced a finished try. A rule that finished above zero on at least 12 cells, before any fee, was tried again with a fee of 0.12 percent per side. Only buys are counted in that second try. 273 rules got it.

The method, the aggregate results and a downloadable table are on the study page. What the desk does with the results beyond these pages is its own.

Before any fee, it was tried on 69 cells, and it placed no trades.

It was not run a second time with a fee. That second pass happens only when at least 12 cells finished above zero before fees. 273 rules got that pass.

Cells tried	69
Cells that placed a trade	0

How to read the result

How to read the number

No cell took a trade, so there is no return to read. The rule above is the whole note.

What this does not show

The useful question is what the rule assumes, how many trades it took, and what happened across coins and chart speeds rather than in one cell.

There is no cell to single out, and this note does not invent one. Other years, another exchange, or another fee would be a different measurement.

Questions about External Signals Strategy Tester

Words used on this page

Backtest

The rule was tried on old prices. No real money moved.

Cell

One coin on one chart speed. Bitcoin every 4 hours is one cell. Bitcoin once a day is another.

Chart speed

How often a new price bar is drawn. 15m means every 15 minutes, 1h means hourly, 4h means every 4 hours, 1D means once a day.

Fee, per side

A cost taken each time the rule trades. Per side means once on the way in and once on the way out.

Median

Line the cells up from the biggest loss to the biggest gain. The median is the middle one. Half the cells did better and half did worse.

Drawdown

The deepest fall from a high point along the way, as a percent of the account at that high.

Above zero

The account finished with more than it started.
